Cipher Basics
What is the first part of a Cipher-X code called?
The Key Letter
Decode P8956. What are the letters from the single digits?
G, C, F, D
Is A8273 valid?
Yes
You decode a real word, but it dosen't include the Key Letter. Valid?
You decoded the letters K, T, I, E, and the Key Letter is A. What is a valid final word?
KATIE
Must the number of digits in a Cipher-X code be odd or even
Even
Code T9283: What are the pair numbers letters?
92: N
83: E
Is K843 valid?
No, it has an odd number of digits
A digit pair gives a repeated letter. What do you do?
Use the Key Boost to get a new letter.
Final letters: T, R, A, P, the Key Letter is P. Is "PART" valid?
Yes, it's a real word and includes the Key Letter.
What do you do if you decode a digit and get the same letter twice?
Use the Key Boost, add the Key Letter's number
Decode L3846. What are the single-letter results?
C, H, D, F
Is M2E64 valid?
No, digits must be numbers only
Boosted Letter = Key Letter. Still valid?
No, the Key Letter cannot get crossed off, repeat the Key Boost trick.
You crossed off: A, E, F, I, K, T. Can you make the word "RANK"?
Not valid, you can't use the K or A because those are crossed off.
What do you do when the pair number is bigger than 26?
-26 until it is under 26 or divide by 26.
A digit repeats: 4 shows up twice. Key is R. What happens?
4+18 = 22 -> V replaces the repeated 4
Is Z87423901 a valid Cipher-X code?
Yes
A student says their word is valid but it's not in the dictionary. Valid?
It's invalid, the word must be real
A student decoded "O, L, A, K" with Key Letter M. They guessed "LOOK", valid or not?
Not valid, it dosen't use the Key Letter.
Name 2 rules that make Cipher-s code invalid
Not enough digits, odd number of digits, no Key Letter in final word, more than 1 letter.
Here's a Cipher-X code: L384625. What's one valid final word using the Key Letter?
ex: Fluid
I'll check urs
Make your own invalid code and explain why it dosen't work
I'll say
You decoded everything but can't form a word. Why not?
You likely made a mistake or the code was invalid.
You want the word "DANGER" to be the answer. Create a valid Cipher-X code (Key Letter D) that could decode to it.
Let me check.
